Multi-port end-fire beam controllable planar antenna and antenna system

A multi-port planar antenna system is described that has digital reconfigurability to adjust the beam directing functionality of the system. Herein, a substrate is provided, and a grid of parasitic elements is printed on a surface of the substrate. One or more drive radiating elements, such as monopole antennas or dipole antennas, are printed on the substrate proximate the parasitic elements. The switching elements between adjacent parasitic elements are then configured to direct the radiation direction in a particular direction in the azimuth plane. The small form factor of the planar antenna system may be used in multiple input multiple output (MIMO) applications used by fifth generation (5G) devices such as mobile phones, Internet of Things (IoT) devices, and vehicles. 本文描述了一种多端口平面天线系统，其具有数字可重构性以调整该系统的波束引向功能。提供基板，并且在所述基板的表面上印制寄生元件的栅格。一个或多个驱动辐射元件，例如单极天线或偶极天线被印制在基板上靠近寄生元件。然后相邻寄生元件之间的开关元件被配置成在方位平面中沿特定方向对辐射方向进行引导。该平面天线系统的小形状因子可以用在由诸如移动电话、物联网(IoT)设备和车辆等第五代(5G)设备所使用的多进多出(MIMO)应用中。
